To all whom it may concern.

Be it known that I, HENRY M. PIGKERING, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented a new and useful Composition for Preventing theAccumulation of Moisture of Condensation upon Glass or other Protectedsurfaces, of which the following is a specification.

The present invention relates to improvements in a composition forpreventing the accumulation of moisture of condensation upon glass orother polished surfaces, the same being especially desirable for use inconnection With automobile Wind shields, locomotive cab Windows, carWindows, ships pilot house windows, show Windows, head lights, and suchsimilar surfaces.

The composition consists of the following ingredients which are combinedin the proportions stated, to wit :potassium oleate, M parts; glycerin(pure), parts; oil of turpentine, 1 part; oil of eucalyptus, 1} part.

In mixing the above ingredients, the po tassium oleate and glycerin aremixed and cooked over a sand bath until melted together. The oil ofturpentine and eucalyptus are then. added, being thoroughly stirred andWhile heing stirred are cooked over a hot fire until the compound burnsslightly. The mixture should then be tested upon a cool surface and ifof a dark brown color and of a consistency of glue, it is ready to pourinto tubes.

In using the above composition, it is applied directly to the surfacedesired and there spread by means of a cotton cloth evenly over theentire surface. it may also he applied by saturating the cloth with thecomposition. I

The amount to he used varies according Specification of Letters Patent.

Application filed April 24, 1914. Serial No. M4324.

to the purpose for which it is used, and such surface after having thecomposition appllield thereto is rubbed lightly with a dry 0 0t It hasbeen found in practice when the above composition is properly appliedthat it does not retard the vision or reflection, but that it Willprevent the accumulation of condensation upon the surface of the glassand thus overcome a great objection to the use of glass in the variousplaces outlined.

This composition has been used with suc cess upon dental mirrors,surveying instruments, eyeglasses, binoculars, and glass upon show casesand refrigerators Where it has prevented the collection of condensationthat would render the glass blurred or translucent.

What is claimed is:

1. A composition for preventing the accumulation o moisture ofcondensation upon glass or other protected surfaces, composed ofpotassium oleate, glycerin, oil of turpentine, and oil of eucalyptus,substantially in the proportions described.

2. A composition for preventing the accumulation of moisture ofcondensation upon glass or other protected surfaces, composed ofpotassium oleate, approximately M parts; glycerin, approximately 10parts; oil of turpentine, approximately one part, and oil of eucalyptus,approximately one half part.

In testimony that If claim the foregoing as my own, if have heretoafiined my signature in the presence of two witnesses.
